SPECIFICATION forming part of Letters Patent No. 425,503, dated April 15, 1890.

Application filed April 9, 1889. Serial No. 306,631. (No model.)

T0 at whom, it may concern:

Be it known that I, JOHANN GLAss, of Leipsic, in the Kingdom of Saxony, Germany, have invented an Improved Bow for Stringed Musical Instruments, of which the following is a specification.

This invention relates to an improved bow for stringed musical instruments, and more particularly tothe manner of attaching the hair to the frog and tip.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved bow. Fig. 2 is a bottom View thereof with slide f partly cut away. Fig. 3 is a side view of the tip; Fig. 4, a section on lineVV, Fig. 3; Fig. 5, a section on line U U, Fig. 1; Fig. 6, a side View of the frog; Fig. 7, a section on line IV V, Fig. 6; and Fig. 8, a section on line X X, Fig. 6.

The letter A represents the handle or stick of the bow, terminating at one end in the tip A, and provided at the other end with the adjustable frog A The hair B is provided at each end with a knot or is enlarged or thickened in an equivalent manner, as at t' and a.

The frog A is provided with a longitudinal groove 1), into which opens a downwardly-extending slit (1. The knot (L is passed into groove Z), while the hair passes down and out through the slit d. The groove Z) is closed by slide 6, and the slit dis closed by slide f.

The tip A of the bow is provided with a transverse groove g, communicating with the downwardly-extending slit h. The knot i is passed into the groove and the hair projects out of the slit. A slide 70 serves to close the groove g.

The advantage of this bow is that the hairs are all subjected to the same tension and that they can be readily inserted.

\Vha-t I claim is- 1. The combination of handle A with frog A having a groove and a slit communicating with the groove, and with the hair 13, having a knot that is received by the groove, substantially as specified.

2. The combination of handle A, having a tip, with a frog, the tip and frog being provided with grooves and communicating slits, and with hair l3,being knotted at the ends to be received by the grooves, and with the slides c f 71', substantially as specified.

I11 testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
